To determine the prevalence of multiresistant organism (MRO) colonisation of reusable venesection tourniquets.
A prospective study in a tertiary hospital to collect and analyse reusable venesection tourniquets for the presence of MROs - methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant enterococci (VRE), and extended-spectrum β-lactamase and metallo-β-lactamase-producing Enterobacteriaceae - using a sensitive enrichment method. Tourniquets were collected and tested during a 10-week period between September and November 2010.
Prevalence of MRO colonisation of tourniquets.
The overall colonisation rate of 100 tourniquets randomly collected from general wards, ambulatory care areas and critical care areas was 78%. MROs were isolated from 25 tourniquets collected from a variety of hospital locations, including general wards, the intensive care unit, burns unit and anaesthetic bay. MRSA was isolated from 14 tourniquets and VRE from 19; both MRSA and VRE were isolated from nine tourniquets. There were no microorganisms isolated from 22 tourniquets.
Reusable tourniquets can be colonised with MROs and may be a potential source of transmission of MROs to hospitalised patients.
确定可重复使用的静脉采血止血带中多耐药生物体（MRO）定植的流行率。
在一家三级医院进行的前瞻性研究，使用敏感的富集方法收集和分析可重复使用的静脉采血止血带是否存在耐甲氧西林金黄色葡萄球菌（MRSA）、万古霉素耐药肠球菌（VRE）以及产广谱β-内酰胺酶和金属β-内酰胺酶的肠杆菌科。在 2010 年 9 月至 11 月的 10 周期间收集和测试止血带。
止血带中 MRO 定植的流行率。
从普通病房、门诊区和重症监护区随机采集的 100 个止血带的总体定植率为 78%。从各种医院地点（包括普通病房、重症监护室、烧伤病房和麻醉区）采集的 25 个止血带中分离出 MRO。从 14 个止血带中分离出 MRSA，从 19 个止血带中分离出 VRE；9 个止血带同时分离出 MRSA 和 VRE。22 个止血带未分离出微生物。
可重复使用的止血带可能会被 MRO 定植，并可能成为 MRO 向住院患者传播的潜在来源。
